&lt;!-- TWO STEPS TO INSTALL RANDOM COLORS:

   1. Paste the first code into the HEAD of your HTML document
   2. Put the last coding into the BODY of your HTML document  --&gt; 
	    
&lt;!-- STEP ONE: Paste this code into the HEAD of your document  --&gt;

&lt;HEAD&gt;

&lt;SCRIPT LANGUAGE="JavaScript"&gt;

&lt;! &gt;
&lt;! &gt;

&lt;!-- Begin

document.fgColor=256*rnd(255)+16*rnd(255)+rnd(255);
document.bgColor=256*rnd(255)+16*rnd(255)+rnd(255);
// End --&gt;
&lt;/SCRIPT&gt;

&lt;!-- STEP TWO: Paste this coding into the BODY of your HTML document  --&gt;
